MM54HC154/MM74HC1544-to-16 Line DecoderGeneral DescripTIonThis decoder uTIlizes advanced silicon-gate CMOS technology,and is well suited to memory address decoding or datarouTIng applicaTIons. It possesses high noise immunity, andlow power consumption of CMOS with speeds similar to lowpower Schottky TTL circuits.The MM54HC154/MM74HC154 have 4 binary select inputs(A, B, C, and D). If the device is enabled these inputs determinewhich one of the 16 normally high outputs will go low.Two active low enables (G1 and G2) are provided to easecascading of decoders with little or no external logic.Each output can drive 10 low power Schottky TTL equivalentloads, and is functionally and pin equivalent to the54LS154/74LS154. All inputs are protected from damagedue to static discharge by diodes to VCC and ground.FeaturesY Typical propagation delay: 21 nsY Power supply quiescent current: 80 mA (74HC)Y Wide power supply voltage range: 2±6VY Low input current: 1 mA maximum
